Quick Answer<\/strong><\/p>\n

Four IPOs open on 15 October and close on 19 October, with anchor bidding on 14 October, allotment around 21 October and listing on 23 October, and issue sizes range from Rs 475 crore to Rs 5,012 crore. Bonfiglioli Transmissions has a price band of Rs 558 to Rs 586, Tonbo Imaging Rs 665 to Rs 700, Sahajanand Medical Technologies Rs 327 to Rs 344 and Zetwerk Rs 143 to Rs 151, and each needs about Rs 14,650 to Rs 14,950 for one retail lot. The only IPO GMP I could find was Rs 30 (about 19.9%) for Zetwerk on an undated page, which implies a listing near Rs 181 (my calculation), and I could not confirm reliable figures for the other three. Grey market premium is an unofficial indicator, so weigh the business quality, valuation and financials, and note that Zetwerk is loss-making and Tonbo’s latest quarter was a loss.<\/p>\n<\/p><\/div>\n

IPO GMP, or grey market premium, is the first thing many investors check, but it changes by the hour and is not recognised by SEBI or the exchanges. This week is busy because four issues open together, which splits investor attention and money.<\/p>\n

This guide compares the four IPOs side by side: dates, price band, issue size, lot size, structure, financials, and the IPO GMP where available, plus what to check before you apply.<\/p>\n
